Showa Denko Waste Plastic and Chemical
Recycling Projects• Productization of low-carbon hydrocarbons, ammonia, and CO2 through recycling plastics• Loading approximately 200 t of plastic daily; processing approximately 60,000 t of plastic. (Processing approximately
10% of container recycled plastics from households)• Obtained eco-mark certification as a manufacturing process for the first time in Japan.

processing record• Stable production has continued for 17 years since 2003; approximately 900,000 tons of plastic has been recycled todate.
• The ammonia raw material ratio has reached 50% thanks to improvement of equipment and operation technology.
• Economically established thanks to subsidies from the Ministry of Economy, Trade and Industry during the initialconstruction and continued recycled plastic containers (variable assistance)

Demonstration Project with McDonald's
In December 2020, as a demonstration project to promote the recycling of plastic in Kawasaki City, a demonstration
project was implemented to recycle plastic from an inner-city McDonald's store into hydrogen and to reduce it to theelectrical power of an electric motor cycles for couriers.

As a part of our cooperation in the demonstration test of a new vehicle
using hydrogen for the East Japan Railway (JR East), on June 3, 2019,
three companies, JR East Japan, Japan Freight Railway Company (JR Freight), andShowa Denko, signed a basic agreement for the demonstration test.
(Showa Denko plans to provide plastic-derived low-carbon hydrocarbons in the Ogimachi area.)
March, 2022: Scheduled to start the test
